My low back hurts when doing ab exercises (mostly crunches).

rest a few days, drop crunches for planks

Crunches arnt good for your back, try any other ab exercise such as any hanging ab work, the ab bench machine thing, planks, twists. Like literally anything but crunches

>>41747692
Crunches are mainly a hip flexor exercise, and if you have any lower back lordosis you are basically pulling your lumbar vertebra with the iliopsoas muscle, which contributes to the hip flexion movement. You should do the crunches like this: lay on your back with knees on around 90 degrees flexion, this removes the lordosis from your lower back. Start crunching vertebrae by vertebrae, reach your dick with your chin, and once you've reached the end of comfortable movement range, slowly back down to where you started. That's a proper ab crunch, for abs only, not for the hip flexors.

>if you have any lower back lordosis
I kinda have due to bad posture in my early years

Thanks for the tip senpai, I'm try to strengthen core and work on my posture, but right now crunches and the likes weirdly feel like a back workout. I'll try that form

Crunches are shit, replace with planks and hanging leg raises.

>>41747692
Deactivate your hip flexors by activating your hamstrings. You can do this by planting your feet flat on the floor and trying to drag them towards your ass.

Drop crunches for planks and ab wheel exercises. Leg raises don't seem as bad for you back as crunches if you have a perfect form, but they aren't as "safe" as the other alternatives listed.

Planks are not good for your lower back.

>lower back lordosis
any way to fix this?

This anon knows. Dragon flags too, ditch the crunches. They are shit tier
Work your muscles in the way you are using them. You want to have your core straight, not hunched over, your spine bent, like when you do crunches. See how your core tenses up when you squat.

if you live anywhere near Phoenix, Arizona I will teach you my method to develop abs and other various muscle groups without lifting or calisthenics, or any traditional movements at all. I will train you in my ways for 20 bux/hour

Sounds good, I'll be there in 30 minutes

You most likely have tight Quadriceps and hip flexors these muscles pull your lower back into hyperlordosis which causes pain in the vertebrae. So stretch those muscles. The pain comes when you try to do abs but use hip flexors instead.

try doing
>ab crunches with legs up (pic related)
>cable crunches

Focus on moving your upperbody towards your lower body and not vice versa, slow and controlled make sure you exhale during each rep
